I firmly believe involving family is not the way to go.
I don't see how HIS therapist can talk to you.
You cannot control this and his mom/therapist really can't help you win back control.
The person who cares least about the R controls it. Think about it.. over the course of a few days you have contacted a DB Coach, pondered about meeting with Michelle, asked about having your H watch a DVD... all signs you are looking for control.
Control you... your actions and reactions. It is all you can do.
